Abstract (en)
[origin: WO2021078397A1] The present invention relates to an apparatus and method for multi-level encoding of an input message sequence into a symbol sequence, for instance, based on polar coding. The input message comprises information bits. The apparatus is configured to divide the input message into a plurality of sub-messages, encode each of the sub-messages into a codeword, wherein a set of the sub-messages is encoded on the basis of the codewords obtained by encoding the sub-messages not in the set and a predefined function of the symbol sequence, and map the encoded sub-messages into corresponding symbols.
